3 Bit Comparator Boolean Expression. It consists of four inputs and three outputs to generate less than equal to and greater than between two. 2 bit magnitude comparator.
A comparator used to compare two binary numbers each of two bits is called a 2 bit magnitude comparator. Subtraction using adder. A is the most significant bit msb and b is the least significant bit lsb in the logical.
The logic circuit of a 2 bit comparator how to design a 4 bit comparator.
By using these boolean expressions we can implement a logic circuit for this comparator as given below. 1 bit magnitude comparator using complementary cmos circuit. The logic circuit of a 2 bit comparator how to design a 4 bit comparator. A three bit magnitude comparator has two inputs a 2 a 1 a 0 and b 2 b 1 b 0 an integrated circuit magnitude comparator 7485 would actually have four inputs but the karnaugh map below needs to be kept to a reasonable size.
